Paul,
Here's what I think I know.
Ford TFI ignitions are designed to run with the spark timing controlled by
a computer.
The TFI module sends a "PIP" (think of it as points opening) signal to the
computer and the computer sends a "SPOUT" (think of it as Fire-The-Coil)
signal to the TFI module. In the absence of a "SPOUT" signal, the TFI module
will produce sparks at a fixed crankshaft timing.
Your description of how the engine runs sounds, to me, like you are
running with fixed ignition timing.
Exactly which model of Holley TBI do you have?
